Application filed November 20, 1913. Serial No. 802,064.

T0 all whom t may concer/:t

Be it known that I, THOMAS H. KENNnY, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an 1mprovement in Waste-Valves, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a waste valve for lavatories, bath tubs, and the like, and is embodied in a novel construction and arrangement of the operating parts whereby the actuating handle is in the form ofa lever which operates in the direction in which the valve moves, the connecting parts being wholly inclosed so that the device is.

not only neat in appearance, but is easily kept clean.

In accordance with the invention,` the waste valve itself is provided with a seat at the bottom of the bowl or tub, and is opened by being lifted from the seat, the said valve having a downwardly projecting stem which is actuated by a lever enteringN the waste passage below the valve. The said lever, which is rocked on its fulcrum to raise and lower the valve, is provided at the fulcrum point with a ball made in two parts which are adapted to be pressed apart by a spring inclosed inside of the ball parts and which extend around the lever, the said ball fitting in a socket, a part of which is formed in a lateral branch from the waste passage, while the other part is formed in a coupling piece adapted to be secured upon said branch.

rThe two parts together are shaped to form a socket for the ball, and the spring compensates for any wear, holding the parts of the ball firmly in engagement with the walls of the socket, thereby making a thoroughly water tight joint.

The detachable socket piece is provided with an extended portion which constitutes a stop for the lever, thereby limiting the movement thereof and preventing the ball joint from moving far enough to allow the joint between the two parts of the ball to pass beyond the solid portion of the spherical socket. This lever is connected by a link with a pivotally supported handle which is so arranged that it can be contained in a closed housing formed in a single piece, said housing havingy a slot through which the lever projects, and a detachable sleeve which forms a guide for the link.

Figure 1 is a vertical section of a lavatory supplied with a waste valve embodying'the invention; Fig. 2 is an enlarged sectional detail of the valve itself showing the valve as opened, instead of closed; and Fig. 3 is a horizontal sectional detail on the line s of Fig. 1.

Referring to Fig; 1, the valve seat 1 is` formed at the upper part ofa flanged nipple 2- which projects downward through an opening in the bottom of the lavatory A, the lower part of the said nipple receiving a coupling member 3 which is interposed between the nipple and the waste pipe 4. The upper part of the nipple 2 is provided with lateral openings 5 to receive water from the overflow passage 6 which is formed, as usual, in the body of the lavatory itself, so that any water rising above the desired level will fiow out under the valve 7 which lits the seat 1. The said valve 7 is pro-vided with a valve'stem 8 which projects downward into the coupling 3 and is guided in a spider 9 which is formed in the nipple 2. The stem 8 of the valve is provided at its lower end with a stirrup 10, which is engaged by an operating lever 13, which projects laterally from the coupling 8 through a guide passage or chamber 13. The lever 12 is provided with a hemispherical portion 14 having a cupped recess 15 around the outer portion of the lever, the said hemispherical portion fitting in the end of the lateral passage 13, which is shaped to fit the spherical surface of the said portion 14.

The recess within the portion lll is adapted to contain a spring 16. and the pivotal support for the lever 12 is completed by a second hemispherical piece 17 which has a recess to receive the opposite end of the spring 16, and an opening which surrounds the outer portion of the lever 12, whereby the part 17 can be put into its necessary position.

With the parts assembled as thus far described, the lateral passage 13 is closed by means of a coupling piece 18 which is screwed on the outside of the part 13, the said coupling piece having a spherical recessed portion at its outer end which fits over the movable part 17, as clearly shown in the drawings. The coupling member 18 is further provided with an extended sleeve portion 19, theinner diameter of which is larger thanthe diameter of the lever 12, so as to admit of the operation of the lever, the end of the` sleeve, however, constituting a stop which prevents the hemispherical portion 17 from being moved a suiiicient distance` 'tov allow the joint between the said portion and the part 14: to pass beyond the solid wall of the socket. By this construction, a watertight fit is assured, the spring acting to keep the parts of the ball or sphere in watertight engagement with the socket, the bearing, moreover, having sufiicient frictional engagement to cause the valve 7 to stay open or closed until positively moved by the actuating lever 20. f

In the construction shown the actuating lever 20 extends through a slot 21 formed in a small casing 22 which is made of a single piece of material, the lever being pivoted on a transverse screwethreaded pin 23, extending through the casing across the slot.

At lthe bottom of the casing there is a threaded opening 24 which receives a threaded guide 25 for a link 26 which connects the lever 20 with the lever 12. The means for Vconnecting the lever 2O with the link 26 are best shown in Figs. 1 and 3, the link 26 having a lateral projection 27 which engages in a Slot 28 in the lever 20. There is sufficient lost motion when the lever and the link are free, that is to say, when the pivot screw 23 and the guide 25 are removed, to connect the lever with the lateral projection 27 it being impossible, however, for the parts to become disconnected after the guide and the pivot are in place. The guide 25 is shown as provided with an external screw thread and with a iiange 29, so that the said iange and a nut 30 constitute the means for clamping this part of the device in the flange of the lavatory.

What I claim is:

The combination with a waste valve; of a pivotally supported lever to operate said waste valve; a link connected with said lever, the upper end of said link being cut away at one side and provided with a lateral projection; a. guide sleeve for said link; an inclosing casing connected with said guide sleeve, and having a small lateral opening; and an actuating lever having a cylindrical hub portion approximately fitting said opening and being pivotally supported therein, the inner end of said lever being cut away at one side and having an elongated slot which engages with the lateral projection from the link.

` In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
